CHARLES ALTON WILSON, OF CAMDEN, MAINE.

MARINE PORT-SCREEN.

To all whom it may concern:

Be it known that I, CHARLES ALTON WIL- SON, a citizen of the United States, residing at Camden, in the county of Knox and State of Maine, have invented a new and useful Marine Port-Screen for Yachts and all Vessels Carrying Ports for Ventilation.

My invention is for the purpose of screening ports of vessels aforesaid, allowing said ports to remain open for ventilation, and preventing the ingress of all insects, mice and other small animals and other things that may come through an open port when the vessel is at sea, lying at anchor or at a dock, or when hauled up for any purpose. I attain these objects by the screen illustrated in the accompanying drawing, in which AC represents the rim of a round screen made to fit tightly into the port, said rim being made of sheet copper or brass and being one inch wide. The rim bevels from A to C one eighth of an inch all the way around so that the width or diameter of the screen at the side A is one quarter of an inch greater than its diameter at the side C. The rim is turned outward into a flange all around the edge A, said flange being about three-eighths of an inch wide from A to B. The rim is covered on the side A with a fine bronze wire screening or netting which passes over the edge of the flange B and is soldered to the under side of said flange. The size of Specification of Letters Patent.

Serial No. 332,761.

the screen is to be made to correspond with the size of the port that it is designed to fill.

The screen is adjusted by pressing it into the port from the inside until the rim between A and C brings up on the inside of the port, the bevel of said rim causing a friction that holds the screen firmly in position.

That end of the rim of my improvement which is increased in diameter, as clearly shown at the right of the drawing, serves as a stop to limit the movement of the device in a port-hole and also forms a means by which the device may be conveniently grasped when it is desired to remove the same from a port hole. It will also be observed that said end further serves for the connection of the screen of reticulated material and thereby leaves the remainder of the exterior of the rim smooth, whereby'it is adapted to be fixed by frictional contact in a port hole.

I claim:

As a new article of manufacture, a port hole screen consisting essentially of a rim increased in diameter at one end, said large end portion being bent outwardly to form a flange, and a reticular body arranged across the rim at the large end thereof and secured to the under face of the flange.
